Reenforced metal jamb



March 14, 1933. BAUM REENFORCED METAL JAMB Filed April 7, 1930 I-j7ZZ/7%7 I [54.06 .22 19am Patented Mar. 14, 1933 UNITED STATES ISAACAQBA'UISE, OF CHICAGO, ILLINOIS nnnnrononn manning Y 1 Application filedApril 7,

My invention relates to building construction and more particularly tometal jamb construction. I

An object of my invention is to provide a metal jamb of channel shape inwhich the side plane of the flanges shall be coincident with the planeof the plaster and still provide a firm and unyielding engagement withthe masonry wall. It is common to provide jamb structures of the full.width of the plaster or a great width, in order to insure properdecorative effect, but such structures should include the importantfeature of rigid mounting relative to the wall.

Thus plaster cracks occur adjacent to the junction between the j ambstructure and the plaster.

I have accomplished the desired result in a very simple manner and atthe same time 2 provide for the connection of an effective wall anchor.

The invention will be more readily understood by reference to theaccompanying drawing, in which I Fig. 1 is a sectional view inperspective of a device constructed in accordance with my invention;

Fig. 2 is a horizontal sectional view therei Fig. 3 is a sectional viewin perspective of a modified form of the device shown in Fig. l; and

Fig. 4 is a horizontal sectional view there- By reference to thedrawing, it will be seen that my invention comprises a channel shapedmetal frame, generally indicated at having the web 11, and door stop 12,and channel flanges 13. The metal frame is adapted to overlie and beseparated from a tile wall 14. Connected to the web and flanges is thebracing member 15,,having the spacing portion 16. The bracing member isadapted to have direct contact with the faces of the tile 14. Ifdesired, the anchors 17 may be provided having the hooks 18 adapted tobe inserted in suitable apertures 19 provided in the bracing members 15.The anchor is inserted between two'tile and is embedded in mortar, thusproviding 1930. serial No. 442,245; I

While it is possible that one skilled in the constructionhereingillustrated may devise variations and modifications in the construction shown, and I do not wish to be limited except as indicated inthe appended claims.

side faces of the flanges and web to provide a box section at thecorners of the jamband their web portions in rigid engagement with anunplastered portion of the masonry wall, and wall anchors engaging saidstrips.

2. A metal frame structure comprising a channel-shaped jamb member theflanges of which are adapted to embrace the sides of an unplasteredportion of a masonry wall in spaced relation thereto, the side plane ofthe flanges adapted to lie coincident with the plane of a plasteredportion, of the wall and flanged filler members rigidly secured to saidjamb member and adapted to directly engage said unplastered portion ofthe wall.

3. A metal'frame structure comprising a channel-shaped jamb member theflanges of which are adapted to embrace the sides of a masonry wall inspaced relation thereto, a

flanged filler having one flange connected to a flange of the jambmemberand another flange connected to the web of the jamb member and a webintermediate said flanges adapted to directly engage an unplasteredportion of said wall.

4. A metal frame structure comprising a channel-shaped ambmember theflanges of which are adapted. to embrace the sides of a masonry Wall inspaced relation thereto, a channelshaped filler .having its. flangescontacting withone of the flanges of said jamb member and the outer faceof its web ,adapted to rigidly engage" an unplastered portion of saidwall whereby upon assembling said structure with said wall saidstructure rigidly engages'said wall.

5. In combination With a masonry wall, a metallic frame structure, saidstructure comprising a metal .channebshaped. jamb having substantiallystraight flangesadapted to embrace said wall,,tl1e side plane of theflanges adapted to liecoincident with the planefof a plaster portion ofthe wall, a

flanged filler member rigidly secured to said j amb member and disposedin close engagement with an unplastered-portion of said wall.- I

In testimony whereof I have afiixed my signature,
